Abstract: 708,873. Gyroscopic apparatus. SPERRY CORPORATION. Feb. 27, 1952 [Feb. 28, 1951], No. 5140/52. Class 97(3) A gyro-compass which comprises a rotor case pivoted with freedom of angular movement about two mutually perpendicular axes in a follow-up support by means of an intermediary vertical ring, one of the axes being vertical and the other horizontal during normal operation of the compass, and damping means arranged to apply, on tilt of the rotor case, a torque to the rotor case about the vertical axis acting to reduce the tilt, has gravity responsive torque applying means arranged to apply an opposing torque to the rotor case about the vertical axis when a gravity responsive means is deflected by acceleration of a magnitude in excess of a predetermined value. The compass shown is supported as usual by gimbals in a binnacle, the rotor case 21 being journaled in vertical pivots on the vertical ring 24 by a hollow shaft 32 through which passes an anchored suspension wire 34, and the vertical ring being mounted on horizontal trunnions 26, 26<SP>1</SP> in the follow-up support 12. Meridan seeking properties are applied to the compass by liquid containers 38 secured on the north and south ends of the rotor case 21 and interconnected, by pipes 40, 42. These containers are circular in east-west elevation to prevent drift of the centre of gravity of the liquid in each thereof during tilt. The compass may be damped by a weight 44 on the west side of the rotor case 21 or wholly or partly by adjustable masses 45<SP>1</SP> on the arm 47 of armature 46 of follow-up controller 23. To prevent acceleration forces from causing tilt of the rotor case, an arm 58 secured tc ring 24 supports a liquid container 62 within which a pendulous U-shaped member 54 is pivoted at 56, one arm of this pendulum carrying an adjustable weight 54<SP>1</SP> and passing through a fork in a member 68 attached to the rotor case 21. Engagement of the pendulum with member 68 occurs only when the acceleration forces exceed a predetermined value and causes an opposing torque to be applied about the vertical axis. Specification 706,434 is referred to.

Title: A method for the preparation of alloys
IPC: C25C5/02
Filed: 1949-03-01
Abstract: 666,586. Electrolytic preparation of alloys. AMREIN, W. March 1, 1949 [March 3, 1948], No. 5555/49. Class 41. [Also in Group II] In a method for the preparation of alloys, of which the constituents are capable of forming water-resistant amalgams and at least one of which is difficultly soluble, or insoluble, in mercury, a metal the amalgam of which is electronegative to the amalgam of the alloy to be obtained is selected to be treated electrolytically with mercury (as cathode) in a closed circuit, the quantity of said metal being small, for instance 0.1 per cent, the resulting amalgam being caused to react in a continuous process with a solution of metallic salts comprising alloy constituents, and the resulting compound metallic amalgam being separated out of the circuit and freed from the mercury by heating. The metal selected may itself form one of the constituents of the alloy. In the arrangement shown, an amalgam is formed in an electrolytic cell A using a metal salt solution and a mercury cathode, the amalgam flowing to a chemical reaction cell B in two compartments I, II. Into compartment I a metallic salt solution containing alloy constituents enters by way of inlet 5 and is discharged through outlet 6. Another metallic salt solution containing alloy constituents not as soluble in mercury as those in compartment I, is supplied through inlet 7 to compartment II and is discharged through outlet 8. The alloy constituents form an amalgam with mercury, displacing the metal provided in the electrolyte cell A. The amalgam is subjected to filtration, centrifuging or like treatment to separate the amalgam from mercury, which is returned to the electrolytic cell. The mercury in the amalgam is expelled by heating. Examples are given of the production of brass powder using zinc amalgam produced in the electrolytic cell, of the production of a powdered alloy of iron, nickel, and manganese, using a sodium amalgam, and of the production of a powdered alloy of manganese and copper, using a sodium amalgam.

Abstract: 180,064. Lancashire Dynamo & Motor Co., Ltd., and Stansfield, W. Feb. 19, 1921. Coils and conductors.-In squirrel-cage windings for dynamo-electric machines wherein the faces of the conductor bars that make joint with the end connectors, and the jointing-lugs of the latter are normal to or inclined at a considerable angle to the plane of rotation, the bars are so shaped at one or both ends that the corresponding ends of adjacent bars may be connected together and to the one jointing-lug. The invention is specially applicable to end-ring connectors of the type described in Specification 13504/08. In the preferred construction illustrated in Fig. 3, each bar is bent at one end only as at c2, c3 so that a part c4 abuts against the straight end of the adjacent conductor, and a narrow axial gap c1 is formed at each extremity; a series connection is thus obtained around the core. The lugs d1 formed by twisting the teeth d2 of the end rings D fit into the gaps c1, and the joint is made by brazing, riveting, &c. In a modification, alternate bars are straight throughout their length, the remainder being bent at each end so as to connect with the two adjacent bars at opposite ends. Another form of the invention is described in which pairs of adjacent conductors are joined together at both ends.

Title: Power slip unit for supporting well pipe
IPC: E21B19/16
Filed: 1976-02-16
Abstract: 1528683 Well pipe slip assembly VARCO INTERNATIONAL INC 16 Feb 1976 [18 Feb 1975] 05961/76 Heading E1F A set of well pipe slips is adapted to grip a well pipe while positioned above a rotary table and can then be moved into a bowl in the table by lowering the pipe. In the embodiment shown slips 62, 63 are connected by hinges 64, 65 to a central slip 61 carried by a plate 77' pivotally connected at 79 to an arm 50 which in turn is pivotally connected to a carriage 31 and is movable between operative and retracted positions by ram 57. The carriage is freely movable along a vertical column and is biased to an upper position by counter weight 40. A further ram 98 for moving slips 62, 63 between open and closed positions has its rod pivotally connected to arm 103 fast with slip 62 and its cylinder pivotally connected to an arm 100 fast with slip 63. A further arm 17 pivotably mounted on the column carries a pipe spinner 18 and a torque wrench 20. Operating mode: When it is necessary to set the slips, a pilot valve 120' (Fig. 12) is operated to cause relay valve 122 to pressurize line 129. Ram 57 accordingly moves arm 50 to its operative position, in which the slips encircle a drill pipe, and then valve 143 directs fluid to ram 98 to cause the slips to grip the pipe. If the pipe happens to be off-centre when the slips engage, the free end of one of slips 62, 63 will abut the pipe and cause plate 77' to rotate against torsional spring bias, to an extent limited by stop 94, so that the slips are positioned to grip the pipe upon actuation of ram 98 as above. Once the slips are engaged with the pipe, the pipe is lowered to locate the slips in a bowl 73, the rod end of ram 57 being disconnected from valve 122 by valve 133 as the arm 50 moves away from its upper position. To release the slips, the pipe is picked up and then valve 120' is operated to cause valve 122 to pressurize line 128 so that ram 98 opens the slips. The counter weight raises the arm 50 to its upper position, if the pipe travel does not achieve this, and upon resetting of valve 133 ram 57 returns arm 50 to its retracted position.
